Abstract
A wireless communication system includes a processor that receives a downlink control information (DCI) associated with a transmission channel used for transmitting a RF signal and a control channel element index associated with the DCI. The processor determines a scrambling code based on the control channel element index for the DCI, scrambles the DCI using the scrambling code, generates a scrambled DCI, and modulates the scrambled. DCI to generate a modulated symbol. The processor uses look-up tables to determine a resource element group (REG) based on the control channel element index, map the modulated symbol to the REG, and generate a transmission frame.
